泛型约束可以使用在方法中吗?
public abstract class DataAccess<TDataTable, TDataContext> : IDisposable
  where TDataTable : class, new()
  where TDataContext : DataContext, new()
  {
}

///如何在某个方法中使用?

 public abstract class DataAccess {
  public void NewData<TDataTable, TDataContext>()
  where TDataTable : class, new()
  where TDataContext : DataContext, new()
  {}
}

------解决方案--------------------
可以，类似的

C# code

public static void OpTest<T>(T s, T t) where T : class
{
    System.Console.WriteLine(s == t);
}
static void Main()
{
    string s1 = "foo";
    System.Text.StringBuilder sb = new System.Text.StringBuilder("foo");
    string s2 = sb.ToString();
    OpTest<string>(s1, s2);
}
